1. Optimal Skill Diversity in Teams (Co-authored with Miaomiao Dong, Vladimir Smirnov, Olivia Taylor, and Andrew Wait)

The paper studies how the optimal diversity of skills and expertise in teams depends on the team’s objective. The authors show that different approaches to evaluating team performance may lead to substantially different optimal levels of diversity: when the focus is on the worst-case scenario, optimal diversity is no lower than when performance is evaluated in terms of expected output. Accordingly, one of the paper’s conclusions is that greater skill diversity can be achieved not through direct management of team composition, but by setting a minimum acceptable level of quality or performance.

2. On the Repeated Volunteer's Dilemma with Equal Cost Sharing (Co-authored with Rabah Amir, Huizhong Liu, and Jingwen Tian)

The paper studies a repeated volunteer’s dilemma — a situation in which a single volunteer is sufficient to provide a public good, while the cost of volunteering is shared equally among all volunteers. The authors show that in the one-shot game all pure-strategy Nash equilibria involve a single volunteer, whereas in the infinitely repeated game, under certain conditions, all Pareto-optimal coalitions of volunteers can be sustained. In terms of efficiency, the scope for cooperation, and the equitable distribution of costs, the most attractive scenario is one in which all players volunteer in every period.
 

We wish Tatiana continued academic success and many more brilliant publications!
